摘要:基质隔离红外光谱和量子化学计算结果的结合表明,Nbo 2分子在固体稀有气体基质中形成nbo 2(ng)2(ng = Ar,Xe)配合物时,由两个稀有气体原子协调.相反,Tao 2分子不能形成类似的稀有气体络合物.铌和二氧化钽还与双氧反应形成侧键结合的超氧二氧化物配合物mo 4(m = Nb,Ta),它们在固体氩气基质中被一个氩原子配位.在形成mo 6和mo 4时,Mo 4(ar)中配位的ar原子可被o 2或xe取代(xe)配合物.结果表明,应将捕集在固体稀有气体基质中的nbo 2,Nbo 4和tao 4分子视为nbo 2(ng)2和mo 4(ng)(ng = Ar,Xe; M = Nb,Ta)配合物而不是"分离的"金属氧化物.

权利人:IBM; REPSOL SA
摘要:Disclosed is a rapid, reproducible solution-based method to synthesize solid sodium ion-conductive materials. The method includes: (a) forming an aqueous mixture of (i) at least one sodium salt, and (ii) at least one metal oxide; (b) adding at least one phosphorous precursor as a neutralizing agent into the mixture; (c) concentrating the mixture to form a paste; (d) calcining or removing liquid from the paste to form a solid; and (e) sintering the solid at a high temperature to form a dense, non-porous, sodium ion-conductive material. Solid sodium ion-conductive materials have electrochemical applications, including use as solid electrolytes for batteries.

权利人:FRAS LE S A
摘要:A preparation of niobium nanoparticles, its use, and a process for obtaining it by comminution, that is, a top-down process. The preparation of nanoparticles has a particular composition, purity, granulometric profile, and specific surface area, being useful in a variety of applications. Also taught is a process for obtaining nanoparticles of mineral species containing Niobium, through controlled comminution and without chemical reactions or contamination with reagents typical of the synthesis of nanoparticles. The preparation of niobium nanoparticles provides the large-scale production of niobium pentoxide nanoparticles with high purity, determined granulometric profile and very high specific surface area, enabling its use in practice in several industrial applications.

标题:Multiblock copolymer films with inorganic nanoparticles, methods of making same, and uses thereof
发明人：WIESNER ULRICH; GU YIBEI
权利人:UNIV CORNELL
摘要:Asymmetric organic-inorganic films and methods for forming and using such films. For example, the films are used as membranes for selective separation applications. The methods combine co-assembly of block copolymer (BCP) and inorganic nanoparticles (NPs), such as, for example, titanium dioxide (TiO 2 ), with non-solvent induced phase separation. The resulting films exhibit structural asymmetry. For example, the films have a thin nanoporous surface layer on top of a macroporous finger-like support layer. Parameters that may dictate membrane morphology include the fraction of inorganic nanoparticles used and the length of time allowed for surface layer development. In filtration tests, the resulting membranes show both desirable selectivity and permeability. The synthesis methods for hybrid membranes provide a new self-assembly platform upon which multi-functional and high-performance organic-inorganic membranes can be formed.
